To use County/City tax rates, you must first activate the Extra Feature. Once purchased, this is available when State/Zip Code/Manual is set to "State".
Sales tax can be calculated based on the customer's state, county/city, or zip code. If your tax is charged by county/city then select your state and type the county or city value here.
Then enter the tax rate into the Sales Tax box and click Add.
Note: This is an optional feature. Contact your local tax adviser to find out if you need to charge tax based on your local county/city rates.
